SMOKE-CONSUMER.

To all whom it concern: t

Be it knownthatl, Gimme Soiunrssn, a citizen of the United States, and a resident of 'Gulfport, in the county of Harrison and State ofMississippi, have made certain new and useful Im rovementsin Smoke -'Consumers, of whic the following is a specificaman...

-,,i My invention is an improvement in smoke consumers, and consists in certain novel constructions, and combinationsof parts, hereinafter described and claimed. The object of the. invention isto provide ,asimple and inexpensive device of the character specified, for attachment to heating plants, for perfectly; jconsuming all of the combustible portions of the fuel, by passing the products of combustion repeatedly tli rough the fire box, with a suitable mixturev to i i 1 'Referring to the drawings forming ajpart hereof, Figure 1 is a front view of the improvement applied ,to a battery of boilers, a

part thereof being broken away. Fig. 2 is a view of a portion of Fig. '1, at right angles tothe said figure, 3 1s a side view of the nnprovement' appli to a locomotive, partly broken away-,-and Fig.1 41 is an end view of Fig. 3, from the front. 1

' The embodiment, of the invention shown. in Figs. 1 .and 2, is'shown applied to a battery of boilers .1 and 2, having a commonstack 3, to which the fire boxof the boilers .del'izveneanh fire boxhaving a door 1. The staok;3-i sprovided at its upper end with a reducedportion 5, having at its free end an elbowfi. 1

Afan casihg'fZ-i's arranged adjacent to the boilers, and the shaft 8 of the fan is provided with aj'pulley 9 for connection'with a suitable source of power to run the 'fan. A

tubular casing 10 communicates with one side of the fan casing by an elbow 11, and

the said casin section from t e fan casing to its free end which-is bell-shaped as shown at 12.

.'Ad]'acent to the bell, he tubular casing is doubled" upon itself as at 13, so that the bell is substantially parallel with the casing, and

the elbow 6 of the reduced'portion 5 of the stackextends-into the ball, as shown in Fig. 1, the elbow having the same curve as the tubular casing and being arranged at the center thereof. i

The edge "of the bell 12 is provided with .1 an internal annular flange 14, which extends gradually increases in cross.

x Specification 02 Letters Patent. Patented Aug, 5?, 1911), Application filed lay 11; 1910.' Serial No. 580,589. I l I inwardly and upwandly toward the stack, and the free edge of theiflange is spaced apart from the outcr surface ofthe stack as shown to form an annular air passage 15 be tween the flange and the stack.

Near itsbottom, the fan casing 7 is provided with a laterally extending discharge pipe 16,, graduallyincreasing in cross section from the fan casing an x beizig'zbentat right anglesat 17 to ass'downwar y. to-

wardthe 'fire' box. At it's-lowerend llhQjdlS- f' charge pipe divides into branch pipes 18 and 1 19, each of which extends laterally at right anglesfrom the inner pipe, and each branch again divides in branches as indicative at 20. The ultimate branches of the pipe 17 c0rrespond'in number to. the number of thefire boxes, each of the said: ultimate branches opening into a fire box above the door 4, so. t at the unconsumed gases'and the like are passed through the fire boxes by the fan.

As the gaseous products of combustion pass from the stack, they are mixed with a suitable quantit of air, and returned to the xfirle :box under orced draft by the fan, and

this process is repeated until every particle of combustible material is oxidized. Sufficient air is passed into theJfi-rebox to insure combustion, sothat the full he'at-value of the fuel is obtained. T

In Figs. 3 and 1, the stack 21 of the boiler H 22 is providedat' its free end with a rearwardly bent e1bow"23, and the fan'casing 24 is arran ed' at the rear" of the boiler. The shaft 25 o the fan is provided with a pulley 26, connected by a belt 27 with a moving part of the engine, and a tubular casing28 connects the fan casing with the stack.

The casing '28 gradually increases in cross section from the fan casnig'to the stack, and adjacent to the stack is bent down- Wardly at 29, openin into a bellxBO which incloses the stack. n internally andupr wardly extending annular flan e 31 is arranged at the'edge of the bell, and extends toward the stack, the free edgeof the flange loo being spaced apart from t lic stack to form;-

an air passage 32.

The curve of the elbow 23' of the stack follows that of the bend 29 of the tubular casing, and adjacent to the end of the elbow,

the angular portion 29 of the tubular casing is provided with an opening 32,which is encircled by a funnel-shaped ange 33: A bafile plate 34 is secured to theinneri-face: of

the tubular casing below the opening 32",

and directs the air entering above the opening of the elbow 23.

{rho-discharge pipe 35 of the'fan casing leads from near the bottom thereof, and opens into the fire box 36, of the locomotive a ove the level of the fuel 37 by an" elbow 38. The inlet pipe in both cases opens into the fan casing axial to the fan shaft. In the operation of the construction shown in Figs. 3 and 4, the products of combustion pass in the direction of the arrows the fuel isutilized.

It will be evident that the construction shown in Figs. 1 and 2 might be provided with the opening 32 in the hell or hood of the tubular casing or pipe leading from the v stack to the-fan casing. In stationary heating plants however, the opening would be of slight advantage. The bends in the stack and tubular casing are on arcs of large circles, so that but little friction is offered to the passage of the products .Ofcombustion.
